“…The axial forces at the base of the side columns N c are the summation of the shear forces in the links V link,i (i = 1, …, n links ) with n links the number of links for each column (typically equal to the number of storeys). A parameter significantly influencing the structural behaviour of the considered HCSW is the coupling ratio CR [2], defined as the ratio between the base moment resisted by the lateral columns M c and the total overturning moment M c +M w . The procedure adopted in this work for the design of the case studies was developed during the INNO-HYCO research project [1] and takes inspiration from the ASCE recommendations [2] for conventional hybrid coupled shear walls [3].…”

A novel 2-level yielding steel coupling beam (TYSCB) has been developed to enhance the seismic performance of coupled shear wall systems. The TYSCB consists of a shear-yielding beam designed to yield first under minor earthquakes and a bend-yielding beam designed to yield under severe earthquakes. A comparison of seismic behavior of 4 20-storey coupled shear wall structures with reinforced concrete coupling beams, complete steel coupling beams, fuse steel coupling beams, and TYSCB is presented. The dimensions and force-displacement curves of these coupling beams are first designed. Nonlinear dynamic analyses on these structures are carried out under minor and severe earthquakes. The seismic behavior of these models is studied by comparing their storey shear forces, storey drift ratios and ductility demands. The results show that the base shear and storey drift of the structure with TYSCB under both minor and severe earthquakes are less than those of structures with concrete coupling beams and complete steel coupling beams. Furthermore, the ductility demand of coupled shear walls with TYSCB subjected to severe earthquakes can be greatly released compared with those using fuse steel coupling beams. This indicates that the proposed TYSCB has a better balance between ductility demand and energy dissipation, compared to traditional steel coupling beams.

“…For this reason, di erent techniques have been proposed instead of conventional coupling beams [13][14][15][16][17][18][19][20][21][22][23]. Some researchers have turned to steel coupling beams, with their ends embedded in two adjacent walls, instead of reinforced concrete coupling beams [13,[16][17][18][19][20]. Steel coupling beams possess the necessary combination of ductility, strength, and sti ness, needed for providing the best overall structural performance and suitable hysteretic response.…”

“…In addition, it is more advantageous to design them as shear yielding members or shear critical, since such members have more desirable energy dissipation; such a choice is not possible for reinforced concrete coupling beams. El-Tawil et al developed design recommendations for steel coupling beams in RC shear wall [20].…”

Abstract. Construction of diagonal reinforcement in concrete coupling beam is di cult; therefore, its replacement is steel coupling beam. A review of the related literature shows that a few studies have considered seismic behavior of RC coupled wall with steel coupling beam. In this paper, the in uence of an increase in building height on the seismic nonlinear behavior of dual structural systems in the form of RC frames accompanied with RC coupled shear walls once with concrete, and then with steel coupling beam was investigated. Therefore, the buildings with 7, 14, and 21 stories and containing RC coupled wall systems with concrete and steel coupling beams were used to perform the pushover analysis with di erent load patterns. Some seismic parameters, such as ductility factor, response modi cation factor due to ductility, over-strength factor, response modi cation factor (R), and displacement ampli cation factor (C d ) were studied. Regarding the results, the response modi cation factor for the mentioned structural system is higher than the values used in codes of practice for seismic resistant design of buildings. In addition, the displacement ampli cation factor and the response modi cation factor increase as the structure height decreases and the values of these factors at steel coupling beam structures are higher than those at concrete coupling beams.
